Dr. Bobby CorriganDr. Bobby Corrigan enthralled us all once again with another great presentation. His report on how climatic events affect rodents was fascinating. We know that climate can impact rat populations.   Hurricane Sandy relocated and reduced rat populations. Mild winters usually result in larger populations later in the season due to increased reproductive rates and lower mortality. There are reports around the world of increased rat activity. Could this be due to warmer weather patterns?

There’s been a lot of talk lately about how many rats are believed to be in New York City. Some reports indicate there’s 1 rat for every person. According to Dr. Corrigan, that statement cannot be supported. There is no science behind it. We can get a good idea of a rat population within a specific location in a neighborhood through proper monitoring, but a census cannot be determined for an entire city.
